Prompt Injection Vulnerability of Consensus Generating Applications in Digital Democracy
Large Language Models (LLMs) are gaining traction as a method to generate consensus statements and aggregate preferences in digital democracy experiments. Yet, LLMs may introduce critical vulnerabilities in these systems. Here, we explore the impact of prompt-injection attacks targeting consensus generating systems by introducing a four-dimensional taxonomy of attacks. We test these attacks using LLaMA 3.1 8B and Chat GPT 4.1 Nano finding the LLMs more vulnerable to criticism attacks -- attacks…

Quantum Quasinormal Mode Theory for Dissipative Nano-Optics and Magnetodielectric Cavity Quantum Electrodynamics
The unprecedented pace of evolution in nanoscale architectures for cavity quantum electrodynamics (cQED) has posed crucial challenges for theory, where the quantum dynamics arising from the non-perturbative dressing of matter by cavity electric and magnetic fields, as well as the fundamentally non-hermitian character of the system are to be treated without significant approximation. The lossy electromagnetic resonances of photonic, plasmonic or magnonic nanostructures are described as quasinorm…

In-situ profiling of pressure-induced exciton traps in suspended MoS$_2$ monolayers
We demonstrate the in-situ read-out of the spatial profile of suspended MoS$_2$ monolayers hosted on substrates with nano-structured holes. As the profiles are spatially bent, the suspended MoS$_2$ monolayers act as exciton traps with tunable luminescence intensity and energy. The tunability is realized by controlling the environmental pressure on the monolayers, which allows to control hundreds of suspended MoS$_2$ monolayers on a single substrate.

A Novel Theoretical Approach on Micro-Nano Robotic Networks Based on Density Matrices and Swarm Quantum Mechanics
In a robotic swarm, parameters such as position and proximity to the target can be described in terms of probability amplitudes. This idea led to recent studies on a quantum approach to the definition of the swarm, including a block-matrix representation. Here, we propose an advancement of the idea, defining a swarm as a mixed quantum state, to be described with a density matrix, whose size does not change with the number of robots.

Optimal robust detection statistics for pulsar timing arrays
Pulsar timing arrays (PTAs) seek to detect a nano-Hz stochastic gravitational-wave background (GWB) by searching for the characteristic Hellings and Downs angular pattern of timing residual correlations. So far, the evidence remains below the conventional $5$-$σ$ threshold, as assessed using the literature-standard ``optimal cross-correlation detection statistic''. While this quadratic combination of cross-correlated data maximizes the {\em deflection} (signal-to-noise ratio), it does not maxi…

Diffusion of gravitactic chiral active Brownian particles in an asymmetric channel
The diffusion of micro- and nano-swimmers in a fluid, confined within irregular structures that impose entropic barriers, is often modeled using overdamped active Brownian dynamics, where viscous effects are paramount and inertia is negligible. Here, we numerically investigate the diffusive behavior of chiral self-propelled particles in a two-dimensional asymmetric channel subjected to an external torque arising from a gravitational field. We reveal the emergence of resonant diffusion when the …

Fast Simulation of Wide-Angle Coherent Diffractive Imaging
Single-shot coherent diffractive imaging (CDI) using intense XUV and soft X-ray pulses holds the promise to deliver information on the three dimensional shape as well as the optical properties of nano-scale objects in a single diffraction image. This advantage over conventional X-ray diffraction methods comes at the cost of a much more complex description of the underlying scattering process due to the importance of wide-angle scattering and propagation effects.The commonly employed reconstruct…

Room temperature giant magnetoresistance detection of spin hall nano-oscillator dynamics in synthetic antiferromagnetic Spin-Valve
Conventional spin Hall nano-oscillators (SHNOs) face fundamental power limitations due to the low anisotropic magnetoresistance (AMR < 0.3%) of ferromagnetic layers. To address this, we developed a synthetic antiferromagnetic spin-valve (SAF-SV) heterostructure [Ta/NiFe/Ru/NiFe/Cu/NiFe/Hf/Pt] that enables efficient giant magnetoresistance (GMR)-based detection of SHNO dynamics at room temperature.

Cavity quantum electrodynamics on a nanocapillay fiber using a composite photonic crystal symmetric cavity
We report the cavity quantum electrodynamics conditions using a composite photonic crystal symmetric cavity (CPCSC) on an optical nanocapillary fiber (NCF). The CPCSC is formed by combining the NCF and the symmetric defect mode nano-grating. The maximum channeling efficiency up to 87% is realized by placing the single quantum emitter at the anti-node position of the CPCSC. The current platform paves the way for manipulating single photons with applications in quantum technology.

Do 1-dimensional metals prefer to form even-numbered van der Waals clusters ?
Parallel quasi-one-dimensional metals are known to experience strong dispersion (van der Waals, vdW) interactions that fall off unusually slowly with separation between the metals. Examples include nanotube brushes, nano-wire arrays, and also common biological structures. In a many-stranded bundle, there are potentially strong multi-strand vdW interactions that go beyond a simple sum of negative (attractive) pairwise inter-strand energies. Perturbative analysis showed that these contributions a…
